IR LONG PASS FILTER COATING

Product of IR  Long Pass Filter

The use of infrared optical systems often requires the protection of the exposed front surface for the
impact to the extreme environment. To this end, we provide a carbon (DLC) coating such as diamond, each
of the optical elements. In addition to the anti-reflection effect, the coating is also characterized by external
stress, a very high mechanical strength and high elasticity.

Optical components are coated with the silicon and germanium of 3-5㎛ to 8-12㎛ wavelength range.
In addition to the standard coating, we also provide a customized design.
